WebPred 1 dňom · The results of space–time-coding metasurfaces for electromagnetic wave modulation are demonstrated using matlab. 3. Results and discussion 3.1. The principle and meta-atoms design For visual demonstration, we formulate the incident wave center frequency as f c = 2 THz, modulation frequency f0 = 0.1 GHz, d x = d y < λ c / 2 = 75 μ m. WebOrthogonal Time Frequency Space Modulation Arman Farhang, Ahmad RezazadehReyhani, Linda E. Doyle, and Behrouz Farhang-Boroujeny Abstract—Orthogonal time frequency space (OTFS) modula-tion is a two-dimensional signaling technique that has recently emerged in the literature to tackle the time-varying (TV) wireless channels.
